Application filed July 13, 1920. :SeriaI No. 395,851.

T 0 all whom it may concern: I

Be it known that 1, JOHN S. BRENNAN, a citizen of the United States, andresident of Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in Burners;and I do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention refers to hydro-carbon burners, known to the trade as thewickless type, wherein some form of non-combustible wick is used, suchas asbestos or analogous material.

The primary object of my invention 1s to provide a simple, economicaland effective burner, associated with a wick, which structure, as awhole, will be durable, fool proof and can be produced at the lowestmaximum manufacturing cost, while at the same time, it will function toinsure un1- form distribution of the fuel oil to and through the wickand will also prevent clogwith its consequent imperfect combustion, thewick element being an advance 1n the art over that type, such as 1sdisclosed in Patent No. 1327858 issued to me January 13th, 1920.

Specific ob ects of my invention are:

To provide a strip or ribbon w1ck, wherein the flat wick is normally ofgreater length than the circular area of its assoc1ated burner cup orchannel, to insure a lap jo1nt at its meeting edges whereby anuninterrupted circular flame will result, which de sired feature isimpractical, wherein a ribbon wick is used having a butt-ended oint. Insuch cases, it has been variation between the length of a ribbon wickand the circular burner cup will frequently result in creating a gap inthe jo1nt or break in the flame. Furthermore, bythe lap joint mentioned,the wick can be ignited at anypoint and the circular train of the flamefrom the point of ignition will quickly complete the cycle.

To provide a burner cup for the wick, wherein its flow channel isapproximately equal in width to twice the thickness of the wick, wherebythe la joint of said wick 1s frictionally held in place by. the oppositedemonstrated that side walls of the burner flow channel, and theremainder of the circular flow channel forms a free space for the travelfuel oil between the side surfaces of the wick and one or both sidewalls of the channel, which are spaced from the face or faces of thewick, due to the single thickness thereof at all points except at thelap joint.

To provide a metallic reinforcin means carried by the wick forsustaining 51o same rigidly as to width andfor supporting'said wickabove the bottom of the How channel, into which it is nested, whereby abottom edge and one or both sides of the wick are exposed to the flow offuel oil, so as to insure perfect capillary feed and also to reventchoking of the fuel oil supply not.

To provide the metallic reinforcing strip with end feet projecting aboveupper and lower edges of the same, whereby the said feet, whenoverlapped, will straddle the supply duct and prevent it from choking.

To provide a wick cup wherein the flow channel is horizontally disposed,whereby uniformity in dieing out the blank is assured and the cost ofmanufacture materially reduced, it being understood that train channels,when arranged to slant toward the fuel oil duct, causes complication inthe die work. To also provide the inner wall of the fuel channel with anupward and inward taper to thus widen the mouth of the wick receivingflow chamber, whereby the wick can be more readily slipped into positionin assemblage, and at the same time such incline wall will insureuniformity in drawing the metal blank, and thereafter in shedding thefinished product from the die.

With the above and other minor objects in view, the invention consistsin certain peculiarities of construction and combination of parts, asare herein set forth with refer ence to the accompanying illustrationsand subsequently defined in claims:

In the drawings,

Figure 1 represents a sectional, elevational view of a burnercup andwick embodying the features of my invention, the sect1on being indicatedby line 1--1 of Figure 2.

of the till - feet 9, wh

izontal bottom to the Figure 2 is a plan View of the same.

igure 3 represents an enlarged fragmentary sectional view of the burnercup, having fitted therein the lapped ends of a wick embodying thefeatures of my invention, and particularly illustrating the means forpreventing choking of the oil supply duct.

Figure 4 is a face View and Figure 5 is a modified form of wickreceiving cup, fitted with a section embody ng the broad of cup, thewick is suspended from the horflow channel by indentures, it beingunderstood that the flow channel is of approximately twice the width asthe thickness of the wick.

eferring by character to the drawings, 1 represents a circular Wick cup,the walls of the same being folded upon themselves to wall 3 of thecavity is shown vertically disposed and the inner wall 4 thereof inpractice tapered upwardly and inwardly, so as to develop a V-shapedchamber having somewhat wider mouth for receiving the wick, in

comparison to the width of the flow channel walls 'The inner taperedwalls 4 of the cup are merged into a vented fiat cap piece 5 of theordinary type.

eferring especially to Figures 3 and 4 of the drawings, the wick is ofthe ribbon type, that is,

plied 1n predetermined lengths, the same be circular its ends areoveracross sectional elevation of lapped more or less as shown in Figure2 of the drawings, whereby a double thickness at the point of lap iseffected.

n lapping the wick into the cup cavity, 1 preferably position theoverlapped joint, over the fuel oil supply duct 2', as indlcated inFigures 1, 2 and 3. ence, the legs 8 Will straddle the fuel oil supplyduct 2 and prevent clogging at this point particularly ttom edge of thewick fabric is Figures 1 and 5 of the drawings, when the wick isinserted in position, it will be noted that the flow cavity space fromwall to wall is of approximately the same width as the combinedthickness of the lapped ends of the wick, and hence, the wick at thispoint and associated parts It will be further noted that the remainderof the wick which surrounds the inner wall 4 is spaced both from saidinner wall and f lower edge of the wick is attained, it bein understoodthat in this exemplification of the invention the wick is held from theouter wall 3 by the thickness of the metallic reinforcing strip 6.obstructed wick is, as seen, held a slight distance from the bottom ofthe flow channel by the legs 8 and 9.

As shown in Figure 5, the lower edge of the wic in some instances may beheld in suspension channel 2 by tively, which are formed by denting thewalls of said channel at p I claim ity of legs eXtendin therefrom to apoint beyond the wick e ges and spaced apart along the circumference,and a circular wick cup for the reception of the strip, the legs of saidwic being adapted to rest upon the bottom of the cup for holding thewick edge in suspension and permitting fuel to reach said edge and thesides of the wick.

weenie 2. The combination of a ribbon wick adapted to be folded incircular shape and having its ends lapped to form a double thickness atone point, a cup therefor having a fiow chamber including a horizontallydisposed bottom and a vertically tapered inner Wall, the base of whichchamber is of a width equal to the thickness of the wick at its lappedends, and means carried by and extending below the wick for supportingthe 10 bottom edge of the same at a predetermined height from the bottomof the fiow chamber.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, in

the county of Milwaukee, and State of Wis- 15 consin.
